Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed September 15, 1915. Serial No. 50,772.

To all whom it may concern.

Be it known that I, WILLIAM E. SILVER- rHoRNn, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pour-Outs, of which the following is a specification.

This invention relates to a pour-out for bottles and the like, and the object thereof is to provide anew and improved device of this character which will be substantial and attractive and which may be manufact'ured inexpensively.

A further obiect is to provide improved means for operating the movable closure associated with the pour-out. v

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this. specification, and in which I have shown a merely preferred form of embodiment of the invention: Figure 1 is a transverse vertical sectional view through a pour-out constructed in accordance with the provisions of this invention, the same being illustrated as applied to a bottle. Fig. 2 is a side elevational view of the pour-out shown in Fig. 1. Fig.

7 3 is a view similar to that shown in Fig. 2,

but illustrating the closure device thrown open. Fig. 4 is a bottom plan View of the pour-out; and Fig. 5 is a fragmentary detail view illustrating the shape and operation of the closure device and associated parts.

Referring to the drawings for describing in detail the structure illustrated therein, the reference character L indicates the body of the pour-out. This isformed with a liq uid outlet conduit G and an air inlet conduit H therethrough, said conduits being substantially parallel throughout their length and curving laterally at their upper ends substantially as illustrated. The air inlet conduit H is made to extend inwardly somewhat beyond the inner end of the liquid outlet conduit G so as to facilitate the entrance of air into the bottle when the bottle is uptilted, The inner end of the sizes as between the conduits being such that a. sufficient quantity of air is admitted through the conduit H to facilitate the discharge of a full flow through the conduit G. a A disk-like portion 2 is formed about the conduits in a position to overlie the upper end of the bottle neck and the outer marginal portion of the part 2 is flanged downwardly, as at 3, so as to surround the upper end of the bottle neck and preserve a neat appearance in case the part 2 does not rest securely upon the upper surface of the bottle neck.

An annular portion 4L is provided below the part 2. for receiving and retaining a gasket 5 of cork, rubber, or other suitable material. The gasket is adapted to engage within the bottle neck in the same manner as would an ordinarv cork stopper and preserves an air tight joint between the pourout and the walls ofthe bottle neck so that the only openings communicating between the interior of the bottle and the atmosphere are the conduits G and H.

In use the bottle is uptilted so that liquid therefrom flows outwardly through the conduit G while air enters through the conduit H. The lateral inclination of the upper end of the pour-out, which is made to conform .to the inclination or curvature of the con duits, serves as an effective indication to the operator as to how the bottle should be held while pouring. Thus the air inlet conduit H is always held above the liquid outlet conduit G and discharges air into the bottle at a point considerably nearer the surface of the liquid in the bottle than any portion of the liquid outlet conduit. A full and uniform discharge through the conduit G is thus insured,

The closure-device is indicated at 6 and comprises a member formed with a hoodlike portion 7 fitted as a gasket 8 for engaging over the upper end of the conduits G and H. The lower end or heel 9 of the closure is turned outwardly at a slight angle and is pivotally connected to the body of the pour-out by means of a pivot pin 10 extending therethrough and through suitable ears 11 formed upon the body. A. spring pressed cap 12 is arranged to engage portions of the heel to hold the closure device in either open or closed position. The cap 12 is received within a socket or guideway 13 and the spring, as 14, rests against the bottom wall of the socket 13 and extends upwardly into the cap 12.

In order to provide a means for retaining the closure either in an open or a closed position and at the same time for provldlng against such a rapid movement of the closure in one direction as to be detrimental to its own welfare or to the welfare of the bottie, the portion of the heel 9 which is en gaged by the spring pressed cap is pref erahly shaped as follows: The surface, as 15 of the heel which is engaged by the cap when the cap is in closing position is in clined so as to engage the cap only at a point 16 which point is somewhat removed from the center line of movement of the cap which substantially intersects the center of the pivot 10. The pressure of the spring being thus exerted at one side of the center line of the pivot constantly urges the upper end of the closure device into tight closing position. This position is shown in Fig. 1 and is shown by light dotted lines in Fig. 5. i As the closure is swung open the part 16 and the nose 17 is forced against the cap 12 so that the cap is pressed backwardly into the socket. As the nose 17 passes beyond the center line, into the position shown by the light dotted lines in Fig. 5, the force of the spring is again exerted to move the closure. This time, however, the force is applied to the opposite side of the nose 17 and urges the closure farther open. This urging continues until the closure device reaches the position shown by the dot and dash lines in Fig. 5, in which position a surface portion, as 18, comes into engagement with the spring pressed cap. The surface portion 18 is made substantially concentric to the center of the pivot pin 10 and the frictional engagement of the cap therewith serves as an easy but effective brake upon the swinging movement of the closure. This substantially concentric surface is continued sufficiently to permit the closure device to move under the braking influence to fully open position as shown by the heavy dotted lines in Fig. 5. The downward or opening movement of the closure deviceis rapid to the point where the braking effect is applied and the momentum gathered is sufiicient to carry it to fully open position. The rapidity of movement is materially slackened after the braking effect is applied, however, and little or no blow is struck by the free end of the closure device against the bottle. The friction present, however, is sufficient to retain the closure device in its fully open position until manually moved agam to closing position. In moving the closure to closing position it is only necessary to manually swing outer surface of the inlet conduit TI. This will prevent likelihood of liquid from the outlet conduit finding its way into the air inlet conduit. It also provides a small vent for the upper end of the air inlet conduit, where the same not engaged. by the flat sin'face of the gasket 8, suflicient to prevent sweatingof the parts, as will be understood.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above de scription or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A device of the class described, comprising a liquid outlet conduit and a closure therefor, said closure being movable into open and closed position, and means for braking the movement of the closure toward one of said positions.

2. A. device of the class described, comprising a liquid outlet conduit and a closure therefor, said closure being movable'into open and closed position, spring means for moving the closure, and means whereby the spring means is adapted to brake the movement of the closure toward one of said positions.

3. A device of the'class described, comprising a liquid outlet conduit and a closure therefor, said closure being movable into open and closed position, spring meansfor moving the closure into closed position, said spring means serving also to move the closure to open position, and means whereby said spring means will brake the movement of the closure before the closure reaches fully open position.

4. A device of the class described, comprising a body member having an air inlet and a liquid outlet conduit therethrough, a closure for one of said conduits comprising a member pivotally mounted upon the body a socket formed in the body member adjacent the pivot of the closure, a spring pressed member arranged within said socket to engage the pivotal portion of the closure, the pivotal portion of the closure being shaped so that said spring pressed member will urge the closure into closed position or open position and said pivotal portion being further shaped so that said spring pressed member will serve as a frictional brake to retard the movement of the closure toward one of said positions.

5. A bottle stopper, comprising an outlet conduit and a closure for said conduit, in combination with a bottle to which said stopper is connected, means whereby said closure is pivotally mounted to swing from a position closing said conduit downwardly and inwardly to a position adjacent a por tion of the bottle, the closure being likely to injure the bottle by contact therewith, spring means arranged for snapping said closure toward its position adjacent the bottle, and HHHIIS for braking the movement oi the closln'e prior to contact of the closure with the bottle.

6, A bottle stopper, comprising an outlet conduit and a closure for said conduit, in combination with a bottle to which said stopper is connected, means whereby said closure is pivotally mounted to swing from a position closing said conduit downwardly and inwardly to a position adjacent a por tion of the bottle, the closure being likely to injure the bottle by contact therewith,

means for urging said closure from an intermediate position toward either its closing or opened position, and means for braking movement of said closure prior to contact of the closure with the bottle during the opening movement of the closure.

7. A device of the class described, comprising a body having an extension projecting substantially vertically upward therefrom being formed with a conduit therethrough, a closure pivotally mounted adjacent the juncture of said extension with said body to swing upwardly for closing the upper end of the conduit and being adapted to swing downwardly and inwardly for opening said conduit, pivot carrying means formed at the juncture of said extension with said body upon which said closure is supported, the pivot carrying means being fori'ned with a pocket therein extending in a direction substantially radially from the pivot of said closure, the closure having a heel thereon, resilient means contained within said pocket arranged to engage said heel for snapping the closure toward either of its positions, and said resilient means being also adapted to cooperate with a portion of said closure to brake movement of the closure into one of its positions.
